Hi vera,
Thanks for your help.
But still we will be having problem even 2.6.22 / 2.6.23 comes up.
May i know why should we try linux 2.6.23 ? because
android expects
linux 2.6.25 version or 2.6.27 , 29 to port android
1.0 / 1.5 / 1.6 etc
So working on 22,23 will not help us. we should start from 24/25
version.
If you refer from 2.6.19 to 2.6.23 the imx 27 folder structure (arch/
arm/mach-mx27)is same.
applying patches is not a problem.
where as in 2.6.24 onwards folder structure support for imx27 is not
at all there.
i got some patches for 24, 25 . but i dont know how to appy that.
Because the plain linux downloaded from kernel.org or arm-linux git is
not having the folder structure for imx27 .
In this case how to apply the patches?
The folder structure is supported from 2.6.27 onwards. Almost we did
the changes here. its coming till mounting file system . but blocked
in starting user space process, boot prompt... (waiting to get boot
prompt..... but blocked)
Thanks and regards ,
vels
